Original application filed February 26. 1906. Serial No. 302.948.Divided and this application filed April l. 1907. Serial No. 365.628.

To all whom irma/y concern:

Be it known that we, FREDERICK MOIN- TURF and FRANK T. MCINTURF,citizens of the United States, residing at Mendota, in the county ofLasalle and State of Illinois, have invented certain new and usefulImprovements in Corn-Husking Machines, of

which the following is a specification, reference being had therein tothe accompanying drawings.

Our invention relates to a corn husking machine, and the inventionconsists of the organizations and arrangements of parts hereinafterparticularly described and then pointed outin the appended claims, thisapplication being a division of our application filed February 26, 1906,Serial Number 302,948.

In the accompanying drawings-Figure 1 is aplan view of our corn huskingmachine shown associated with a corn harvesting machine with parts ofthe latter broken away to show the driving mechanism; Fig. 2 is across-sectional view on the line 2 2 of Fig. 1 on an enlarged scale Fig.3 is a sectional view on the line 3 3 of Fig. 1; Fig. 4 is a fragmentaryplan view of the husking rolls; and Fig. 5 is a sectional view of one ofthe folding sections of therake employed in connection with the huskingrolls. i The frame of the machine may be of any suitable character. Inthe present instance it consists of front beam 12, rear beam 13,intermediate beam 14, a side beam 1'5, center beam 16, and a pair ofparallel beams 17 at the side of the machine opposite the beam 15. Abeam 18 is located between the side beam 15 and center beam 16. Thesebeams forming the supporting frame of the machine may be securedtogether in any suitable manner. rIhe frame is carried by a tractionwheel 19 rotatably mounted on an axle 20 suitably sup orted by the beams15 and 18, and a secon( wheel 21 located at the opposite side of theframe.

An inclined gathering board 22 is locatedover each of the beams 17, withtheir front ends extended beyond the front beam 12. These beams aresupported near their rear ends by uprights 23 and at the front by theextended ends of the beams 17. The boards 22 are suitably spaced apart,as shown in Fig. 1, to permit of the passage of the stalks between thesame. The inner edges of the boards 22 at their front ends are curvedoutwardly, as at 24, to provide a flaring mouth to guide the stalksbetween the same and to `der and parallel to each board 22 is a board26, such boards being suitably supported by the frame. The boards 22 and26 provide a supporting frame for the mechanism, such as the chains 27,for gathering the stalks and conveying them to suitable snapping rolls,not shown. To the rear of the front ends of the boards 22 andreciprocating in suitable guides, not shown, on the beams 17 is a cutterb ar 28, suchbar being located under the throat or passage between theboards 22 and 26.

The mechanism for harvesting the corn is made the subject-matter of ourabove recited application, and therefore forms no part of the resentinvention and will not be described 1n detail.

The hub of the wheel 19 is provided with a sprocket wheel 29, and achain 30 communicates motion to a smallervsprocket wheel 31 xed on atransverse shaft 32 suitably journaled on the beams 16 and 18. Thisshaft is provided with a second sprocket wheel 33 loosely mountedthereon to which is adapted a chain 34 communicating motion to asprocket wheel 35 fixed on a shaft`36 also journaled on the beams 16 and18. The

lshaft 36 extends beyond the beam 16 and is provided with a bevel gear37 communicating motion to a similar gear 38 fixed on a longitudinalshaft 39. The shaft 39 is suitably journaled on a stub beam 40 fixed tothe beam 16 and also at its front end on the beam 12. Beyond the beam 12the shaft 39 is provided with a crank wheel 41 to the pin of which ispivoted a pitman 42 connected to and for reciprocating the cutter bar28.*`

The traction wheel 19 communicates motion to the operating mechanism ofthe machine, and in order to throw such mechanism out of action whilethe traction wheel is in moe tion, aI suitable clutch is provided. Tothis end the sprocket wheel 33 is engaged and disengaged by a slidingclutch 43 slidably mounted on the shaft 32 and controlled by a hori-Zontal lever 44.

Referring to Fig. 1 a transverse shaft 45 is `suitably journaled in thecentral beam 16 47 fixed on the shaft 36. After the corn is strippedfrom the stalks by the snapping rolls (not shown), it falls upon thehusking rollers 48 which are journaled in end-bars 49 of the frame. Therollers are parallel and disposed in the same plane and extendtransversely of the machine, as shown in Fig. 1, and are arranged inpairs, and any suitable number of such pairs may be employed, threebeing shown in the present instance. The inner ends of the rolls arelocated under the snapping rolls so that the ears of corn will fallthereon. The shafts of the husking rolls are provided with intermeshingpinions 50, as shown in Figs. 1 and 4, and one of such shafts extendsbeyond its pinion and is suitably ournaled in bearings on the uprights51 and is provided with a sprocket gear 52. As shown in Fig. 3 a shaft53 suitably journaled on the uprights 23 is provided with a sprocketgear 54 which communicates motion through the medium of a chain 55 tothe sprocket gear 52. The shaft 45 is provided at its outer end with asprocket gear 56 which furnishes motion to a sprocket gear 57 on theshaft 53 by means of a chain 58, as is clearly shown in Figs. 1 and 3.

As shown in Fig. 4, each husking roll is provided lengthwise thereofwith alternating annular grooves 59 and radial pins 60, the pins on oneroll of each pair being opposite and cooperating with the grooves of theother roll.y These pins serve to strip the husks from the ears and thegrooves provide clearance therefor, the rolls of each pair being closetogether. 1n order to prevent clogging of the rolls and to render thesame yielding to inequalities of the husks the shaft of one roll of eachpair is mounted in sliding bearings 61, as shown in Fig. 4, and anexpansion spring 62 is employed to react against such bearing to pressthe roll thereof yieldingly against the other roll of the pair. At theout-l let end of the husking rolls is a chute 63 the object of which isto discharge the corn on to the conveyer 64.

At opposite sides of the husking rolls 48 and located above the same isa pair of bars 65. These bars provide a pivoted rakerame and at theirouter ends are mounted on a shaft 66 carried in bearings 67 on suitableuprights 68. Near the ends of the shaft 66. and between the bars 65 aresprocket wheels 69. The inner ends of the bars 65 are connected by ashaft 70 provided with sprocket wheels 71. Chains 72 are carried by thesprockets 69 and 71 and these chains are connected at suitable intervalsby cross rods 73 each having a radial stop pin 74, as shown in Fig. 5.On each rod 73 is a pivoted tooth 75 which consists in the presentinstance of a plate bent into the form of a loop at one end to receivethe rod 73. The loop of each tooth has a slot 76 into which projects thestop pin 74. The function of these teeth is to move the ears of cornalong the husking rollsto bring them under successive action of the pins60 and finally push the ears on to the chute 63. The position of theslots 76 is such that the teeth hang at a trailing angle from the understretch of the chains, as shown in Fig. 3, the teeth preferably beingarrested at such angle by the ends of the slots and so as to just clearthe pins 60. The teeth are free to swing upwardly and rearwardly,however, in the event that the ears of corn pile up on the huskingrolls. These teeth are provided with fingers 77 which serve to assistthe teeth in feeding the ears along the rolls. As the teeth pass fromthe under stretch of the chains around the sprockets 69 they hangvertically, thereby avoiding kicking or throwing the ears outwardly. Onthe upper or return stretch of the chains the teeth fold downwardly onand are supported in a horizontal position by the chains, on which theends of the teeth rest, as shown in Fig. 3.

The rake-frame is yieldingly pressed towards the husking rolls 48 bysuitable contractile springs 78 the lower ends of which are fixed to theframe of the machine while the upper ends are attached to ears 79 on theinner end of the rake-frame. The rake-frame normally rests on stops S0carried by side plates 81 and engaged by the ears 79, and the relasiredby the adjustment of the stops 80, which in the present instance takethe form of screw bolts. In the event of crowding of the ears under therake, the frame will readily yield owing to the springs, and avoidbreakage of the parts. The side plates 81 are located at the sides ofthe rake and designed to prevent the escape of the ears during thehusking operation.

An endless conveyer 82, moving in the di; rection of the arrow, Fig. 3,is located under and extends longitudinally of the husking rolls 48.This carrier consists of suitable side chains connected by slats 83 thechains being passed over end sprockets 84 which are fixed to shafts 85,suitably journaled on the frame. A reticulated or slotted plate 86,secured to side beams 87 by its flanges 88, is located under andprovides a support for the upper stretch of the conveyer 82. The underor return stretch is `supported by a suitably supported plate 89 locatedthereunder.

The rake and conveyer 82 are driven through the medium of suitableconnections with the shaft 45. provided with a sprocket wheel 90-whichtransmits motion through the medium of a chain 91 to a sprocket 92 fixedon a shaft 93 suitably journaled, in bearings fixed to the frame of themachine above the beams 15 and 16, one of which is shown in Fig. 2, asat 94. A stub shaft 95 is journaled on the beam l5 and is provided witha sprocket wheel 96 To this end such shaft isv.95 tion of the teeth maybe regulated as de" which receives motion through the medium of a chain97 from a sprocket wheel 98 on the shaft 93. An idler 99 engaging therear stretch of the chain 97 prevents contact of the latter with theside frame of the husking mechanism. The stub shaft 95 is provided witha bevel gear 100 which transmits motion to a similar gear 101 fixed on ashaft 102 journaled in bearings 103 on the frame of the machine at theend of the husking rolls. The opposite end of the shaft 102 is providedwith a gear 104 which communicates motion to a gear 105 iiXed on theshaft 85 at the outer end of the conveyer 82. Such shaft is alsoprovided with a sprocket Wheel 106 which communicates 'motion throughthe medium of a chain 107 to a sprocket 108 on the shaft 66 of the rake.

A curved trough 109 is located at the receiving end of the conveyer 64under the chute 63 and this trough in the present instance consists oftheextended end of the plate 89. The conveyer 64 may be of any suitablecharacter and the bottom thereof is curved concentric with andextendsinto the trough 109, the receiving end of the conveyer being pivoted onthe shaft 102 and receiving motion from such shaft. The conveyer 64 isdesigned to convey the ears to a wagon or any other point and isadjusted through the medium of a suitable cable 110 connected to a shaft111 pivoted on the uprights 68, such shaft being provided with a crank112 and a suitable pawl and ratchet 113.

In the operation of the machine, owing to the rotation of the huskingrolls 48 and the action of the pins 60, the husks are torn from theears, being discharged on to the conveyer 82 located under the huskingrolls. These husks are carried by the conveyer 82 in the direction ofthe arrow in Fig. 3 and dropped on to the ground over the end of suchconveyer. In the event that any corn is shelled during the huskingoperation it drops between the husking rollers and falls on to the plate86, through the perforations of which it passes to the plate 89. Theslats of the conveyer moving along this plate push such corn into thetrough 109 from which it is removed by the conveyer and discharged intothe receptacle designed to receive the ears of corn. During the huskingoperation the ears of corn are moved along the husking rollers to theoutlet end thereof finally and when completely husked passing throughthe l chute 63 to the elevator.
